Mighty Module MM1005 4-20mA Input Limit Alarm With 24VDC Power Supply For 2-Wire TX
MM1005 4-20mA Input Limit Alarm With 24VDC Power Supply For 2-Wire TX
The MM1005 monitors a DC current input and trips a dpdt, 5 A relay when the input exceeds the desired level. Normal operation has the relay energized for the non-alarm condition and de-energized for an alarm condition. This provides a fail-safe alarm condition for loss of power to the module. Option R reverses this logic. The alarm has a set of red/green LEDs to indicate alarm status.
The module contains a 24 VDC transmitter power supply specifically designed for use with two-wire and other 24 VDC powered transmitters.
The deadband adjustment allows a deadband of 0.5% to 100% of span to be set into the module. The deadband is symmetrical about the setpoint.
The module includes filtering and conditioning to reduce susceptibility to transients and noisy operations.
HI/LO pressure alarm, level/position control.
The module is designed to plug into a standard 11-pin relay socket. Part number MP011 is a molded plastic socket suitable for mounting on a flat surface or in a 2 3/4 inch wide PVC snap track (TRK48). Use CLP-1 hold-down clip if needed. A Killark HK Series explosion-proof housing with dome and 11-pin socket is available (HKB-HK2D-11). A DIN rail socket (part number DMP011) is available.
