Yokogawa IP94-A Communication Modules
The Yokogawa IP94-A, also cataloged as the IP94-A Communication Module, operates as a dedicated hardware component for serial data exchange and protocol translation within distributed control systems.
Hardware Specifications
| Parameter | Specification |
| Model | IP94-A |
| Brand | Yokogawa |
| Origin | Japan |
| Weight | 0.15 kg |
| Dimensions | 85 mm x 90 mm x 40 mm |
| Operating Temp | -10 deg C to +60 deg C |
| Power Consumption | 5 W |
| Communication Protocols | Modbus RTU, ASCII, Binary |
| Data Rate | Up to 9600 bps |
| Number of Channels | 8 channels |
| Power Supply Voltage | 12-24 VDC |
Channel-to-Channel Isolation and Loop Performance
The unit incorporates robust channel-to-channel isolation architecture to eliminate ground loops and common-mode voltage spikes across serial communication lines. Operating on Modbus RTU, ASCII, and Binary formats up to a data rate of 9600 bps across 8 independent channels, the module ensures strict signal integrity and deterministic packet transmission within industrial process networks.
Frequently Asked Questions
Q: Does the IP94-A module support live hot-swap insertion on active system backplanes? A: Hot-swapping is restricted while terminal power is active; system power must be isolated prior to module installation or removal to prevent bus communication faults.
Q: How should communication cable shields be terminated to mitigate EMI? A: Terminate the shielding drain wire to the designated functional earth ground stud on the cabinet chassis while maintaining continuous outer shield continuity.
Field Installation Guidelines
Mount the unit securely within the designated industrial enclosure observing the IP65 environmental protection rating. Route serial communication cabling separately from high-voltage power conduits and AC distribution lines to avoid electromagnetic induction. Verify power supply voltage levels are maintained within the 12-24 VDC range prior to energizing the module.
