MPS48 is a digital controller, with ON/OFF, PID single action and PID dual action (direct and reverse) control. The instrument is equipped with AUTOTUNING function. The instrument allows for RS485 serial communication using MODBUS-RTU communication protocol and a transmission speed up to 38.400 baud. The process value is visualized on 4 red displays, the Set value is visualized on 4 green displays while the outputs status is indicated by 4 leds. The instrument provides for the storage of 4 Set Points and can have up to 4 outputs : relay type or can drive solid state relays type (SSR), or it is also possible to have up to 2 analogue outputs. The instrument can be equipped with an input for the current transformer, working as a Heater Break Alarm function and with a programmable digital input as an alternative to output OUT4.
