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. User's Manual Page 1 3.0 SPECIFICATIONS ELECTROMECHANICAL RELAYS SPECIFICATIONS Maximum Current (AC) 7A@240VAC; 10A@125VAC Maximum Current (DC) 15A@24VDC; 10A@28VDC 4.0 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. User's Manual Page 2 5.0 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. 6.0 INPUT SIGNALS 10,11,12,13 AND 15 the input pin is activated with +5vdc. User's Manual Page 3 7.0 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.
