Technical characteristics
● The A and B channels can be freely programmed via the front keys and JP1 and JP2 to current in the range 0...20 mA or voltage in the range 0...10 VDC.
● Linearized Pt100 temperature input in the range -99...+850°C with 3-wire connection.
● PID on/off controller with accurate setting of the regulation parameters XP (proportional band), TI (integrating time) and TD (differentiating time).
● Functions include PI step and-band controller, dl/dt function and comparator or trip amplifier with an external setpoint.
● 2 relay outputs with a make contact connected to a common point.
● Relay outputs can be installed in PELV/SELV circuits.
● Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate use with PR’s 7023 adaptor and 7024 mounting keying.
