Rated impulse-withstand voltage 2.5 KV
Over-voltage category II
Software class and structure A
Clock
Available in EVJ815 and EVJ825 (with built-in secondary lithium
battery) but not available in EVJ805
Clock drift: ≤ 60 s/month at 25 °C (77 °F)
Clock battery autonomy in the absence of a power supply: > 24 h at
25 °C (77 °F)
Clock battery charging time: 24 h (the battery is charged by the
power supply of the device)
Analogue inputs
2 for PTC or NTC probes (cabinet probe and needle probe)
PTC probes
Sensor type: KTY 81-121 (990 Ω @ 25 °C, 77 °F)
Measurement field: from -50 to 150 °C (from -58 to 302 °F)
Resolution: 1 °C (1 °F)
NTC probes
Sensor type: ß3435 (10 KΩ @ 25 °C, 77 °F)
Measurement field: from -40 to 105 °C (from -40 to 221 °F)
Resolution: 1 °C (1 °F)
Analogue-digital inputs
1 input can be configured for analogue input (auxiliary probe) or
digital input (multi-purpose input)
Digital inputs
1 dry contact (door switch)
Contact type: 5 VDC, 1.5 mA
Power supply: none
Digital outputs
5 with electro-mechanical relay (compressor, defrost, evaporator fan,
auxiliary 1 and auxiliary 2)
Compressor relay: SPST, 30 A res. @ 250 VAC
Defrost relay: SPDT, 8 A res. @ 250 VAC
Evaporator fan relay: SPST, 8 A res. @ 250 VAC
Auxiliary relay 1: SPST, 5 A res. @ 250 VAC
Auxiliary relay 2: SPST, 5 A res. @ 250 VAC
The device guarantees reinforced insulation between each digital
output connector and the rest of the components of the device.
