GPIO

Two D-type connectors are provided handling 8 GP (general purpose) input and output channels, con-

trolled remotely from the control surface. GP inputs are on opto-isolators, GP outputs are on relay con-

tacts.

Connector Pin Assignments:

GPI 1-8 (25-pin D-type, female, UNC 4-40 thread)

Pin Signal ‘GPI 1-8’ Pin Signal ‘GPI 1-8’

1 GPI 1a 14 GPI 1b

2 GPI 2a 15 GPI 2b

3 GPI 3a 16 GPI 3b

4 GPI 4a 17 GPI 4b

5 GPI 5a 18 GPI 5b

6 GPI 6a 19 GPI 6b

7 GPI 7a 20 GPI 7b

8 GPI 8a 21 GPI 8b

9-13 GND (0 V) 22-25 VCC (+5 V/600 mA max.)

GPO 1-8 (25-pin D-type, female, UNC 4-40 thread)

Pin Signal ‘GPO 1-8’ POn Signal ‘GPO 1-8’

1 GPO 1a 14 GPO 1b

2 GPO 2a 15 GPO 2b

3 GPO 3a 16 GPO 3b

4 GPO 4a 17 GPO 4b

5 GPO 5a 18 GPO 5b

6 GPO 6a 19 GPO 6b

7 GPO 7a 20 GPO 7b

8 GPO 8a 21 GPO 8b

9-13 GND (0 V) 22-25 VCC (+5 V/600 mA max.)

Inputs:

Control inputs (GPI Xa/b) are completely independent and electrically isolated. They may be used either

with the internal +5 V DC supply voltage, or with external voltages of 5...24 V DC, regardless of the polarity.

Outputs:

Control outputs (GPO Xa/b) are completely independent, electrically isolated relay contacts, closed if

active. Maximum switching power 62.5 VA / 30 W; max. switching voltage 50 V AC or DC; max. switching

current 1 A. Contact resistance (initial value) is max. 100 mΩ at 6 V DC/1 A.

The +5 V DC supply voltage and/or the ground (GND) terminals, together with the relay contacts, may be

used to generate an output signal.

The total current supplied by all VCC (+5 V DC) pins of the GPI/GPO 1-8 connectors must not

exceed 600 mA.
