USER’S MANUAL VER. 1
M26 – 12RELAY EXPANSION
BOARD Rev. 6.2
OVERVIEW
This board provides 12 electromechanical relays with NO (Normally Open) and NC (Normally Closed) connections; this version can be easily mounted on control boxes using DIN rails and can also accommodate ribbon cables.
FEATURES
- 12 Electromechanical relays with NO and NC positions.
- Use IDC26 to connect to the ESS, M16D (PoKeys), UC300ETH-5LPT, AXBB, C25XP, C94 or C76 (UC300ETH).
- Status LEDs on all relay connections.
- External Enable Pin (EN). The board has a pin that allows you to enable/disable all the relays at once.
- Can be powered and tied to the ENABLE line of the C76, M16D, C25XP (Rev4) C94 and MASSO G3 (M40 Board) through IDC26 ribbon cable. NEW.
- Has terminals to allow access to available input pins.
- Din rail mountable.
- Pluggable Screw-On Terminals.

BOARD DESCRIPTION
Requirements:
It requires a 5VDC @ 0.5Amp
power supply Through IDC26 Ribbon Cable PIN 26 to operate.
WARNING
Overvoltage or reverse-polarity power applied to these terminals can cause
damage to the board, and/or the power source.
ENABLE TERMINAL
The card must be provided with a 5VDC signal to enable operation. This feature
has been added to enable you to control externally the status of the relays of
the card. You can add an external switch to provide the enabling signal. If
using this board with a C25XP, C94, C76, or M16D, a jumper can be left in
place the board will automatically be tied to the enable line of the main
board. So, when the main board becomes active, it will automatically enable
the relay board.
INPUT SIGNALS 10,11,12,13 AND 15
the input pin is activated with +5vdc.
WIRING INPUT SIGNALS
-Wiring inputs using an external 24VDC power supply to keep input
circuit isolated.
Note:
If using a +24vdc a 20K resistor is necessary to limit the voltage as the
inputs can take only +5vdc.
