Slave Expansion Module PCB Only (SEM01-M2)

The Slave Expansion Module allows Comfort II to be expanded beyond 16 Inputs and 16 Outputs. Each Slave contains 8 Inputs and 8 outputs, which can be expanded by connecting LEM01_M2 (8 inputs, 8 outputs) or LEM02-M2 (8 inputs).

 

The SEM01-M2 has a built-in regulated power supply and is the same size as the main Comfort panel. For the SEM01-M2 supplied in the standard metal enclosure look at product code SEP01 (Slave Expansion Panel) or for a larger enclosure size SEP01/EN03.

 

Other than the physical size and input power requirements, the function of SEM01-M2 and SEM02-M2 are the same.

Zone Inputs

• 8 fully programmable zones expandable to 16 with Local Expansion Module (LEM)
• Each zone configurable for 0 or 2 end-of-line resistors
• Up to 32 predefined Zone types to simplify zone configuration
• Surge/Over voltage protection for each zone

Open-collector Outputs

• 8 open collector outputs on main board, expandable to 16 with Expansion module.
• Each output can drive external relay or infrared transmitter for remote control appliances. Relay Modules with 4 relays are available.
• Selectable Pulsed or Steady output activation.
• Programmable Infrared signals (air conditioners, home entertainment) at any output.
• Over voltage and Surge-protected outputs.
• Maximum 300 mA current limit for all 8 outputs on SEM. 300mA current limit for all 8 outputs on LEM01-M2s

Power Supply

• SEM01-M2 has built-in regulated 13.8V voltage supply and battery charging circuit. Supplies 1A DC max to 12V, S12V and outputs combined.
• 12V and S12 outputs are protected by resettable fuse 1.8A
• Quiescent current 50 mA max, 25 mA typical (14V DC supply)

Auxiliary Supply Outputs

• 12V unswitched supply
• S12V switchable supply (programmable for reset operation)
• Note: Both 12V and S12V auxiliary supplies and 8 Outputs have a combined continuous current limit of 1A, protected by common resettable fuse of 1.3A

System Supervision

• Individual Zone tamper (open-circuit or short-wiring) with 2 end of line resistors
• Dedicated 24 hour Tamper input

Input/Output Expansion

Each Slave Expansion Module can be expanded using one of the Local Expansion Modules

• LEM02 - Local Expansion Module 8+0 (8 zones, 0 outputs)
• LEM01 - Local Expansion Module 8+8 (8 zones, 8 outputs)
• LEM03 cannot be used with SEM01/02

Each Slave can support a total of 16 inputs and 16 outputs. 3 SEMs can be installed in a Comfort System, giving a system capacity of 64 inputs and outputs. LEM03 (16 input 0 Output LEM) cannot be used with a SEM, and cannot be connected to the main Comfort panel when a SEM is also installed.

Delivery Note: 1-2 weeks Lead Time Applicable.
