M17035 Parallel Port Digital I/O board for M17034
                       - 8 opto-isolated inputs & 8 reed relay outputs

The 8 channels relay output / photo isolator input board for the parallel port pocket digital I/O module (M17034) provides relay output functions and photo isolator input functions.

The relay output part provides 8 single pole single throw (SPST) relays to drive 8 different output channels.
Each relay channel can be used to control ON/OFF of external devices, to drive external high power relays, to activate alarms, etc.
The photo isolator input part provides 8 photo couple digital input channels,
which allow the input signals to be completely floated and prevent the ground loop.

8 channel digital input and 8 channel digital output box
Supports 8 relay output channels and 8 photo coupled input channels
Allows the photo input signals to be completely floated and prevent ground loops

Built-in screw terminal for easy wiring
LED status indicators
Support information for sensor application

Photo coupled isolated input:
  Input response time: 100us minimum
  Input voltage: 15V DC max. for each opto input channel
Maximum voltage of logical output channel is 15V DC
Maximum sink current of logical output channel is 80 mA.

Max contact rating for relay: 120V AC/DC 1 amp
Attraction time for relay: 3 ms, Fall off time for relay: 2 ms
Isolation resistance for relay: 100M ohm
Life expectancy for relay: 5 million operations at full load
The Normal Open (NO) and Common contacts (COM) of each relay is brought out to the screw connector
Breakdown voltage: AC/DC 500V min

Input Current: 80mA max. for each isolated input
Input voltage: 15V DC max for each isolated input
LED indicates which channel is activated

Isolated or non-isolated modes selectable
Jumpers are used to select isolated or non-isolated mode.
When the jumpers are shorted, the channel is set to
non-isolated mode and when open, to isolated mode.
