TECHNICAL DATA

9.1 Technical data

Box: self-extinguishing grey.

Size: 106 x 90 x 58 mm (4.17 x 3.54 x 2.28 in, 6 DIN modules).

Installation: on DIN rail (it is not supplied by the builder).

Frontal protection: IP 40.

Connections: screw terminal blocks with pitch 5 mm (0.19 in) for cables up to

2.5 mm² (0.38 sq in, power supply, inputs and outputs), 5 poles single line female

connector with pitch 2.5 mm (0.09 in, serial port).

Ambient temperature: from 0 to 55 °C (32 to 131 °F, 10 ... 90% of relative humidity

without condensate).

Power supply: 230 Vac, 50/60 Hz, 4 VA.

Clock data maintenance without power supply: 24 hours (the instrument must

have been ON for 2 min at least).

Alarm buzzer: included.

Measure inputs: 3 (cabinet, first and second evaporator probe) for PTC or NTC probes.

Digital inputs: 2 inputs: one multifunction input (NO or NC contact) and one lock

input, without voltage (they work with 5 mA).

Working range: from -50 to 99.9 °C (-58 to 212 °F) for PTC probe, from -40 to 99.9 °C

(-40 to 212 °F) for NTC probe.

Setpoint range: from -99 to 99.9 °C (-99 to 99 °F).

Resolution: 1 °F with unit of measure in Fahrenheit, 0.1 or 1 °C with unit of measure

in Celsius.

Display: one red LED 3-digit display 13.2 mm (0.51 in) high, compressor, evaporator

fan and cabinet light output status indicators, defrost status indicator, instrument mode

indicator.

Outputs: 5 relays: one 16 A @ 250 Vac relay for one 1½ HP @ 230 Vac compressor

control (NO contact), one 8 A @ 250 Vac relay for evaporator fan control (NO contact),

one 8 A @ 250 Vac relay for first defrost system control (change-over contact),

one 8 A @ 250 Vac relay for cabinet light control (NO contact) and one 8 A @ 250 Vac

relay for second defrost system control (change-over contact).

Kind of defrost: electric and hot gas defrost.

Defrost control: defrost interval, defrost end temperature, defrost maximum length

and defrost interval count mode (automatic, by hand and remote).

Serial port: TTL with EVCOBUS communication protocol, adapt for serial interface

EC IFC 02.
