The unit is electrically divided into 4 parts, with 8 inputs or outputs in each part.
Each part requires a separate voltage supply in accordance with one of the
following alternatives:
• Internal supply, not galvanically insulated from the electronics in cabinet
• External supply, galvanically insulated from the electronics in the cabinet.
Voltage rang 19-35 V DC.
Reserved I/O, see 20X Digital I/O.
Analogue I/O
• Output: 2 voltage outputs
Output voltage 0 - + 10 V
Load > 2 kohm
Resolution 10 mV (10/1024 V)
Accuracy 25 mV + 0.4 % of output signal
The analogue unit requires separate power supply —15V, according to one of the
following alternatives:
• Internal —15V supply, not galvanically insulated from the electronics of the
cabinet only intended for analogue I/O. Internal supply is available in the unit's
connector.
• External supply, galvanically insulated from the electronics of the control cabinet.
Voltage tolerance: ^15%.
Connection points for internal as well as external power supply are available in the
system.
Reserved I/O, see 227 Analogue I/O.
241 RIO board Allen Bradley
Remote link (remote I/O) for communication with Allen Bradley PLC.
With the RIO function, up to 128 inputs and outputs, in groups of 32, I/O, can be
transferred serially to a PLC control system equipped with Allen Bradley 1771 RIO node
adapter. Only digital, system, and remote panel signals can be transferred with RIO.
Connection to RIO is via screw terminals on the inside rear wall of the cabinet.
The RIO board takes up two board slots in the rack.
