I/O boards
Features


Digital outputs
This module can be equipped with 2 or 4 isolated outputs. The digital outputs can detect when a threshold is overcome or can be used for energy pulse emission.

· Number of channels 2 / 4
· ML type: 50 VAC/DC/200mA (OPTOMOS), 2 or 4
  outputs
· MH type: 250 VAC/DC/100mA (OPTOMOS), 2 or 4
  outputs
· RL type: 250 VAC/5A resistive (RELAY), 2 relay outputs

Analog outputs
This module is equipped with 2 analog outputs. The analog outputs can be programmed as 0-20 mA or 4-20 mA and can be used in order to transmit a signal to an external device. For 8 analog outputs see the EM80A module.

· Number of channels: 2
· Type 0-20 / 4-20 mA configurable. Active outputs with no
  need of external power supply
· Load: 300 Ohm max.
· Resolution: 12 bit

Digital inputs
This module is equipped with 4 isolated digital inputs. The digital inputs can be used for the acquisition of energy pulses. The inputs have no need for an external power supply. The value of the pulse is programmable, allowing to count other values than energy.

· Number of channels: 4
· Type: isolated for voltage-free contact
· Max frequency: 10Hz

EBUS fast communication bus
This module allows to extend the possibility of the meter to drive I/O.

The bus communicate with the external device at high speed and make it possible to implement complex functions like EM80A (eight analog outputs)

· Transmission: synchronous serial
· Connection 4 wires
· Length: max 10 m
