 Inor LED-W11 Digital Indicator
The Inor LED-W11 digital indicator is for installation directly in a 4-20 mA loop without need for external power. LED-W11 is designed for field mounting on wall, pipe or DIN rail and has a rugged and splashproof housing. The indicator is equipped with bright easy-to-read LED digits. The scale is easily programmable, without reference signal, by two pushbuttons for any values between -1999 and 9999.
The LED-W11 is equipped with a bright luminous 4-digit LED display, which is easy to read even in the dark. The digits are red and 14.2 mm (0.56") high.
The voltage drop is below 5V. The LED-W11 can therefore be connected to the 4-20 mA loop of any normal 2-wire transmitter with no need for external power. With an accuracy of 0.05 % combined with a low temperature drift the LED-W11 allow for high precision read-outs.
The indication range can easily be scaled. The field mounted LED-W11 is splashproof with two internal pushbuttons. The scale can be set to any range between -1999 to 9999 for 4 to 20 mA input. Scaling operation does not require the use of a specific input signal. Labels for different engineering units are included.
The field indicator LED-W11 can be equipped with an integrated Inor In-Head transmitter of any type.
LED-W11 is equipped with a rugged and splashproof IP 65 / NEMA 4X housing with double cable conduits for convenient installation.
LED-P11 has a splashproof front with IP 65 / NEMA 4X protection. The indicators are designed for ambient temperatures between -25 to +80 °C (-13 to +176 °F). The indicator is HART transparent, which means that it will not interfere with or be disrupted by HART communication over the current loop.

 Inor SR535 Alarm Unit
The Inor SR535 Alarm Unit is built for monitoring Pt100 signals in the process industry. The unit gives alarm functions for either increasing or decreasing temperatures and for certain error states. SR535 provides an output signal, 4-20 mA, which is equivalent to the measurement range.
SR535 is equipped with one output relay, Re 1, with switch over contact for temperature monitoring.
A relay connected for normally active function, Re 2, gives a contact breaking function for sensor breakdowns, supply voltage failure, and measurements exceding 125% of the normal range. Re 2 should only be used to indicate that measurements (and monitoring) may not be correct.
An accurate 4-20 mA output signal is available. The signal is temperature linear and equivalent to the calibrated temperature range.
Configuration changes are made conveniently with jumpers. The following adjustments are available: temperature measuring range (see specifications), High/Low-alarm, the relays normally active or passive functions, alarm delay 0.4 or 2 s, hysteresis 0.5 or 5 %. A voltage outlet and a potentiometer on the front panel are used to adjust the set-point. The set-point can be measured as a voltage from the test outlet. The scale is 0-5 V for 0-100 % of input signal.
The relays "normally active or passive" functions are chosen to suit the use of the monitor. Normally active, with the relay coil activated and the monitor inactive (no alarm), is suitable when the monitor is used to give an alarm signal at error states . This means that in case of a power supply failure the monitor will give an alarm signal (=monitoring out of order). Normally passive is mostly used to provide a trip function to switch off equipment, thus saving costly and unnecessary operational stops. The choice of High or Low alarm functions depends on whether increasing or decreasing signal is to be monitored. Alarms are always indicated by a lighted red LED, independent of configuration. Open or closed relay contacts The choice of open or closed relay contacts is made when connecting the output signal lines.
Comparison of monitored input signals to the adjusted set-point is carried out in two stages using a special principle, which gives a very efficient filtering of transient interference and noise. Reliability in the monitoring system is increased with a dynamic hysteresis, which connects the preset hysteresis when an alarm is monitored. The relays in the SR535 will not give a false alarm when power is switched on. A 15-turn potentiometer insures high definition and stability in adjusted set-point. The hysteresis level can be changed with jumpers on the circuit board.
All connections are made with plug-in screw terminals. Installation is simplified by connection diagrams on the front panel. Compact mounting on DIN-rail SR535 snaps on to a 35 mm DIN-rail and can be mounted with high density.

 Inor SR560 Dual-Channel Alarm Unit
The Inor SR560 dual-channel alarm unit is built to monitor mA or V signals in the process industry. The two channels are fully independent. The SR560 is specially designed for reliable safety triggering without false alarms. High configuration flexibility allows for adaptation to required alarm functions.
The SR560 is equipped with two galvanically isolated monitoring channels. Each channel has an output relay with switch over contact. The functions of the channels can be set independent of each other.
Configuration changes are made conveniently with jumpers. The following adjustments are available for each channel: input type (mA or V), measuring range (see specifications), High/Low alarm, the relays normally active or passive functions, alarm delay 0.4 or 2 s. The hysteresis of the trip function is adjusted with a 15-turn potentiometer in the front. The hysteresis can be set between 0.35 and 80 % of input span.
A voltage outlet and a 15-turn potentiometer on the front panel are used to adjust the set-points for each channel. The set-point can be measured as a voltage from the test outlet. The scale is 0(2)-10 V for 0-100 % of input signal.
The relays "normally active or passive" functions are chosen to suit the use of the monitor. Normally active, with the relay coil activated and the monitor inactive (no alarm), is suitable when the monitor is used to give an alarm signal at error states .
