Regulateur DDR245

Specifically conceived for DIN rail mounting, this controller is configurable for up to 18 sensors, while output options gather relays (including Open/Close logic for valves), SSR, 4…20mA, 0…10Volt (both for control and/or rescalable retransmission of setpoint/process value). Extended power supply 24…
230Vac/dc. Software features include the possibility to launch Tuning by digital input, the optional manual reset of alarm condition ("Limit controller"), Latch-on function for sensors calibration (including load cells), a programmable cycle of 3 steps. Serial communication via RS485/ModbusRTU protocol and load monitoring via amperometric transformer TA are both standard functions. The Memory Card provided with internal battery allows to duplicate parameters and settings within seconds, without connecting the controller to power supply. An additional Memory Card allows also upgrade of firmware.
A Windows®-based software is available to set all parameters on PC and save the programs to/from controllers, for archive purpose and to reduce the time required for start-up.
UL-CSA approved for North-American market.
