To enable CT input, modify parameter 287
• Input for 50 mA amperometric transformer.
• Sampling time 100 ms.
• Configurable by parameters.
Digital inputs can be enabled by parameters.
Close pin "DIx" on pin "+V" to enable digital input.
It is possible to put in parallel the digital inputs of different devices joining
together the 0V pins (9).
Modbus RS485 communication.
RTU Slave with galvanic insulation.
It is recommended to use the twisted and shielded cable for communica-
tions.
Digital output PNP (including SSR) for command or alarm.
Range 12 VDC/25 mA or 24 VDC/15mA selectable by parameter 282
Linear output in mA or V (galvanically isolated) configurable as command,
alarm or retransmission of process-setpoint.
The selection mA or Volt for the linear output depends on the parameters
configuration.
Capacity 5 A (3 A for Q2) / 250 VAC for resistive loads.
See chart below.
Electrical endurance Q1, Q2:
• 5 A (3 A for Q2), 250 VAC, resistive loads, 10
• 20/2 A, 250 VAC, cosφ = 0.3, 1.2x10
