PID Temperature Controllers

PID Temperature Controllers features dual displays & selectable inputs. These PID Temperature Controllers are easy to operate and the out can be ordered for a relay contact, a voltage pulse, or a 4 to 20 mAmp output.

PID Temperature Controllers also excepts various inputs from f thermocouples, 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.

PID Temperature Controllers Features:

• Standard inputs thermocouple, RTD
• Heat/Cool action
• Relay, Triac, DC voltage pulse or current output
• Heater break alarm for monitoring multiple parallel heaters
• Loop break alarm for heater breaks/shorted sensors or relays
