ATR121 Controller Double setpoint

Double-setpoint controller which increases configurability of series ATR110/120 in the same standard size 32x74mm.

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 6KΩ and 150KΩ may also be read with 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 command and one for alarm function, and two outputs configurable by parameter as relay or SSR control. The main relay is 8A (on models with internal transformer 24 or 115 or 230Vac) or 10A (on model with internal switching 12…24Vac/Vdc). The alarm relay is 5A.

Memory card enable quick configuration, reducing error margin.

Software features include ON/OFF or PID+Autotuning control and Heating-cooling PID with neutral zone. A single output (relay/SSR) version is available with serial communication RS485 and Modbus-RTU / Slave protocol for application with supervisory systems.

All models are CSA-UL approved for the North-American market
