Binary inputs and outputs

Binary input and output modules are available in two main versions: with
electromechanical relays and with static outputs (power transistor types). For both of
them, binary inputs are of the same type, insulated with optic couplers.
Inside a REF 542plus unit, only modules of the same type have to be present. It is
not possible to have both static and electromechanical modules.

BIO module with mechanical output relays (version3)

Binary input and output modules type BIO3 are available in several versions.
Voltage range low, with inputs able to withstand a voltage range from 19 ... 72 V
*
DC. The input threshold activation level is 14 V DC.
Voltage range high, with inputs able to withstand a voltage range from 88 ... 132
*
V DC. The input threshold activation level is 50 V DC.
Voltage range high, with inputs able to withstand a voltage range from 88 ... 132
*
V DC. The input threshold activation level is 72 V DC.
Voltage range high, with inputs able to withstand a voltage range from 176 ...
*
264 V DC. The input threshold activation level is 143 V DC.
All above mentioned modules can be equipped with an optional static output (power
transistor) on binary output 7, instead of the normal electromechanical contact. This
static output is usually needed to feed external energy meters with pulses.
To make wiring easier, there are also module versions for the wide voltage range
(high and low) available with the binary inputs minus (-) connected together on the
module by an internal line.
