 Field
Selectable Input/Output Controller features universal
field selectable outputs for the main control output.
The main control output can be selected from a relay
contact, a voltage pulse, or a 4 to 20 mAmp output.
Field Selectable Input/Output Controller also excepts
44 types of thermocouple, RTD, DC voltage and DC current.
In addition these controllers can have 2 independent
alarm contacts that are programmable to be deviation,
process, or set value alarms. The Heater break alarms
utilize an external current transformer that monitors
the heater current and activates an alarm should the
current fall below a threshold value that has been
set by the operator. The loop break monitors and protects
the entire temperature control system. The loop break
alarm will detect Heater Breaks, Thermocouple or RTD
failure, short circuits, or the failure of an operating
device such as a mechanical relay, Mercury Relay or
SSR.
