Legend: GR = Relay output type, GT = Transistor output type.
Highlights
  • Built-in Ethernet (10/100 Mbps adaptive)
  • Built-in RS485 port(s) for field devices
  • Optional analog I/O on XP models
  • 24VDC supply, compact footprint

Quick Selection Guide

Smallest XP (Analog Included)

Choose GR10XP / GT10XP or GR14XP / GT14XP for compact machines with analog I/O.

Standard Digital Control

Choose GR20 / GT20 , GR30 / GT30 , or GR40 / GT40 for pure digital I/O needs.

Need Analog I/O

Choose XP models: GR20XP / GT20XP , GR24XP / GT24XP , GR30XP / GT30XP for built-in AI/AO.

Relay vs Transistor

GR (relay) is ideal for universal switching loads. GT (transistor) is recommended for high-speed switching. Common pairs: GR20/GT20, GR30/GT30, GR40/GT40.

FAQ

Q: What is the difference between GR and GT?

GR models use relay outputs for general loads, while GT models use transistor outputs for high-speed switching.

Q: Which models include analog I/O?

XP models include built-in analog I/O: 10XP / 14XP / 20XP / 24XP / 30XP.

Q: Do all models include Ethernet?

Yes, all models listed include a built-in 10/100 Mbps adaptive Ethernet port.
