Input is configurable for; thermocouples type J, K, S, R, PT100, PTC 1000 Ohm, NI100, NTC 10K (typically used in the refrigeration industry) and PT500/PT1000 (widely used in air-conditioning), signals 0-1V, 0-10V, 0-20mA, 4-20mA. Potentiometers with full scale up to 6KΩ and 150KΩ may also be read, including function “Latch on” for quick calibration and setting of minimum, maximum and zero by frontal keys (see Application notes).

Two setpoints are available, one for control and one for alarm function, and they can be related to two relay outputs or to SSR output. The main control relay output is 8A (on models with internal transformer 24V, 115V or 230Vac) or 10A (on model with internal switching 12-24Vac/Vdc). The alarm relay is 5A (alarm modes: treshold, band, deviation; option manual reset of output for Limit controller function). Open/Close logic for motorised valves.

Software features include ON/OFF, PID+Autotuning control and Heating-cooling PID with neutral zone. A single output (1 relay + SSR) version is available with serial communication RS485 and Modbus-RTU / Slave protocol for application with supervisory systems. Sealing IP65 with frontal gasket. Optional Memory Card to copy all parameters, available also with internal battery therefore not requiring to power up the unit. Software application LABSOFTVIEW for Windows enables setting and monitoring of parameters on PC. All models are CSA-UL approved for the North-American market.
