Slave Expansion Modules provide expansion inputs and outputs to Comfort beyond the extra 8 I/O that is availanle through the Local Expansion Module.
Slaves are connected via the Comfort RS485 Bus (CAT5) so they can be mounted far from Comfort, like on a different level in the building
Slaves have 8 Inputs and 8 Outputs. Either 1 LEM01 (8 inputs, 8 outputs) or LEM02 (8 Inputs) can be connected or LEM03 (16 inputs no Outputs) to a Slave in the same enclosure, so each Slave + LEM can support 16 inputs and Outputs (or 24 Inputs and 8 Outputs is LEM03 is connected). Note the SEM01 can have LEM03 connected only from SEM Firmware 7.118
SEP01 is the full Slave Expansion Module with Enclosure, Transformer and battery charger
SEM01C is the Slave PCB only without enclosure or Power Supply TT01-0022, with battery charging circuit
The SEM01C is connected to Comfort via the KA/KB wires only using CAT5. 12V and COM should NOT be connected as the SEM01 should have its own power supply via the transformer. It also charges its own 12V 7AH battery so the Slave has its own backup battery. The SEP01 can supply 1 Amp to external devices like PIRs and smoke detectors Part Numbers
SEM01C: PCB only not including TT01-0022 power Supply
SEP01C: SEM01C with the EN01D metal enclosure. SEM01C will refer to both SEM01C and SEP01C for functional description.
EN01D: Metal Enclosure 310 x 350 x 95 mm with TT01-0022 Power Supply
EN03D: Metal Enclosure 358 x 375 x 94 mm with TT01-0022 Power Supply
TT01-0022: Power Supply 90 - 264 VAC 550-60 Hz Input, 15V 1.8A DC Output
OP03: Output plug-in submodule for SEM01C with 8 outputs
SEM02C is the Slave PCB without power supply /Battery charging. It needs to get its 12V supply from Comfort
The SEM02 PCB is the same as the Left side of the SEM01, ie without the power supply circuit on the right. The SEM02 is connected to Comfort by wires: 12V/COM, KA/KB via the terminal blocks or the white 4 way cable.
