| EV9411 and EV9412 are digital controllers for general purposes. EV9411 has got: - alarm buzzer - 1 analog input (room probe) for J/K thermocouples or for 2/3 wires Pt 100/Ni 120 probes (according to the model) - one 8 res. A @ 250 VAC digital output (electromechanical relay) for temperature regulation. EV9412 has got: - alarm buzzer - 1 analog input (room probe) for J/K thermocouples or for 2/3 wires Pt 100/Ni 120 probes (according to the model) - two 8 res. A @ 250 VAC digital outputs (electromechanical relays) for temperature regulation. EV9411 can be programmed for cooling or heating operation; EV9412 can be programmed for: - operation with independent first working setpoint and second working setpoint relative to the first - operation with two independent working setpoints - operation with neutral zone - operation with steps. In case of operation with independent first working setpoint and second working setpoint relative to the first and of operation with two independent working setpoints, each digital output can be programmed for cooling or heating operation. The devices look in standard case 96 x 96 mm (3.779 x 3.779 in); the user interface is made of a 3 digits + 4 digits custom display (with function icons) and 3 buttons (set, up and down). Installation is by panel, with the screw brackets supplied by the builder. Through the programming key EVKEY (to order separately) it is possible to make the upload and the download of the configuration parameters. Through a serial interface (to order separately) it is also possible to connect the controller to the set-up software system Parameters Manager or to the plants monitoring and supervision one RICS (via TTL, with MODBUS communication protocol). The use of the device with EVKEY, with Parameters Manager or with RICS is allowed on condition that the controller has got the serial port (by request). Among the several features one also highlights: - frontal protection degree IP54 - possibility to program both the quantity shown by the part at the top of the display and the one shown by the part at the bottom - temperature alarms management - function "lock keyboard". |
