TECHNICAL DATA
17.1 Technical data
Container: grey self-extinguishing.
Front panel protection rating: IP 54.
Connections: removable terminal boards (power supply, inputs and
outputs), 6-pole connector (serial port).
Temperature of use: from 0 to 55 °C (from 32 to 131 °F,
10 ... 90% relative humidity without condensate).
Power supply: 115 ... 230 VAC, 50/60 Hz, 5 VA (approx) or 24 VAC,
50/60 Hz.
Keeping the clock data in a power-cut: 24 h with battery
charged.
Battery charging time: 2 min without interruptions (the battery is
charged by the instrument power supply).
Alarm buzzer: incorporated.
Measurement inputs: can be configured:
• 1 (chamber probe) for J/K thermocouple
if functioning with 1 measurement input;
second input (steam probe) for J/K ther-
mocouple
• 2 (top probe and floor probe) for J/K ther-
mocouple if functioning with 2 measure-
ment inputs
Digital inputs: 2 inputs:
• on/stand-by input in high voltage (230 VAC) with
configurable polarity
• multifunction input, for NO/NC contact (poten-
tial-free contact, 5 V 1 mA).
Range of measurement: from -99 to 800 °C (from -99 to 999 °F)
for J thermocouple, from -99 to 999 °C (from -99 to 999 °F) for K
thermocouple.
Resolution: 1 °C/1 °F.
Digital outputs: 6 relays:
• top (relay K1): 8 A res. @ 250 VAC (NO)
• floor (relay K2): 8 A res. @ 250 VAC (NO)
• utility that can be set (relay K3): 8 A res.
@ 250 VAC (contact in exchange)
• airhole (relay K4): 8 A res. @ 250 VAC (NO
contact)
• steam injection (relay K5): 8 A res. @
250 VAC (NO contact)
• utility that can be set (relay K6): 8 A res.
@ 250 VAC (contact in exchange).
The maximum current accepted on clamp 23 is 10 A.
To set the utility managed by relay K3 and relay K6, see paragraph 4.2.
Other outputs: buzzer output (12 V, max. 20 mA); the output is
activated during alarms and errors, with continuous contribution.
Serial port: port for the communication with the supervising system
(through a serial interface, via TTL, with MODBUS communication
protocol) or with the programming key.
