Features:
- Eight 24 V DC inputs and eight NPN transistor outputs share one remote I/O terminal.
- A Manchester-coded multidrop link exchanges point states with the Remote I/O Master.
- Power, communication, input, and output indicators separate network status from field-point status.
The input side of G700-UMD16 groups eight field signals around one positive common, while photocoupler isolation separates those circuits from the network electronics.
On the output side, one negative common supplies the reference for eight NPN transistor points, so load wiring and input-device wiring remain electrically distinct.
Node addressing places G700-UMD16 on the master polling sequence, and the terminal can be secured either to DIN track or directly with screws.
The Omron G700-UMD16 Mixed Input/Output Remote I/O Terminal may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Channel and Common Organization
- Input group: Eight field inputs return through one positive common before their states cross the photocoupler boundary.
- Output group: Eight NPN transistor points use a separate negative common to switch their connected DC loads.
- Point indication: Individual orange indicators let the operator compare commanded output states with input and load wiring.
- Circuit boundary: Input sensing, output switching, and remote-network electronics remain organized as distinct functional paths.
Master Polling and Node Exchange
- Polling role: The Remote I/O Master calls the assigned G700-UMD16 node and exchanges its input and output data in the network cycle.
- Address setting: The node address identifies which terminal data belongs to G700-UMD16 on the shared multidrop cable.
- Signal coding: Manchester coding carries point-state data over the shielded twisted-pair network rather than through the field commons.
- Network reach: One master can coordinate up to 32 addressed nodes across the documented 500 m cable limit.
Field and Network Connections
- Input return: Connect the eight 24 V DC sensing circuits to their positive common without mixing that return with the output group.
- Load return: The NPN output circuits switch loads referenced to the dedicated negative common and remain limited per point.
- Network pair: B200-TW shielded twisted-pair cable carries the multidrop communication path between the master and addressed terminals.
- Line termination: Preserve cable polarity and shield continuity, then terminate only the documented end of the remote I/O line.
Placement and Operating Boundaries
- DIN-track option: The enclosure clips to a DIN track so its point terminals and status indicators remain accessible inside the panel.
- Screw option: Direct screw mounting secures G700-UMD16 where a rail is unavailable without changing its electrical terminal roles.
- Supply boundary: Feed the terminal from a 24 V DC source that remains within the documented operating range.
- Ambient limit: Locate G700-UMD16 where the operating temperature stays within 0 to 55 °C and corrosive gas is absent.
