| Compact digital controllers for static refrigerating units, with HACCP and Energy Saving functions EVS223 and EVS233 are compact digital controllers able to control compressor and defrost (by temperature-time). The second relay allows to manage one of the folloving users: - on-off output - alarm output. The third relay allows to manage one of the following users: - cabinet light - demisting resistances - auxiliary output. The connection of the loads is immediate. The instrument is provided with two measure inputs both for PTC and NTC probes (cabinet probe and evaporator probe or display probe); a third input can be set to work both as measure input (display probe or condenser probe) and as digital input (multipurpose). The HACCP function allows to store up to 2 alarms supplying information on: - the critical value - the alarm duration. The HACCP alarms the instrument can store are: - the lower temperature alarm - the upper temperature alarm. The Energy Saving function allows to change the working temperature (through the multipurpose input). The instrument is provided with a serial port that allows the communication with supervision systems via TTL (with MODBUS communication protocol) or with the programming key EVKEY; two further communication ports (available by request) allow the communication with supervision systems via RS 485 (with MODBUS communication protocol) and with the remote display EVT100. EVS223 and EVS233 frontal size is 185 x 38 mm (W x H) and have been studied for panel mounting. EVS223 is different from EVS233 because of the 8 A relay instead the 20 A one (to manage the compressor). |
