AFG SPECIFICATIONS
Female 15 way ‘D Type’ Communication Connector Pin Out and Relay Diagram
Relay Electrical
Supply voltage:
The relay is powered from a 5V regulator inside the
AFG.
Input control:
The relay state is controlled via a TTL signal from the
AFG and is in a ‘closed position’ when a logic ‘1’ input
is applied (Signal from the AFG is true).
Relay Output Characteristics (351-063)
Output Function:
Continuity between Red and Blue
wire when AFG output logic is 1
(Signal True).
Peak relay ac voltage:
350 V
Continuous relay load current (PEAK AC): 120 mA
Maximum relay peak load current:
300 mA
Typical relay contact resistance at 100 mA: 17 (Ohm)
Isolation voltage between AFG and relay output: 1500 V ac
Relay Description
Using AFG-PLC cable
The solid-state relay is mounted on a PCB, which is
Part number 351-063
housed in a 15 pin D-type connector.
Connection to the relay output is via a 5 metre length screened cable. The end of the
cable is left with bare wires to allow appropriate termination to the peripheral PLC
device.
