Product Overview
Red Lion Controls GMDIOS (catalog GMDIOS00) expansion module delivers localized DC control capability to host interface racks. Adds eight configurable sinking or sourcing DC sensing channels alongside six high-capacity solid-state switching circuits. Dual side-panel DIP banks provide direct hardware selection for channel polarity and electrical noise suppression. Dedicated front LED indicators give maintenance personnel instant verification of operational health and individual circuit state.
Key Features
- 8 DC inputs individually switch-selectable for sinking (SNK) or sourcing (SRC) operation
- Selectable input filtering per channel via dedicated side DIP switches
- 6 solid-state DC outputs rated 30 VDC at 1 A maximum
- Front faceplate status indicators for module status (STS), 8 inputs, and 6 outputs
- Direct host backplane power connection drawing 3.6 W maximum
- Three removable 6-pin screw terminal blocks for field wiring
- cULus listed for Class I, Division 2 hazardous locations (Groups A, B, C, D; T4)
Applications
- Expanding local sensor and switch monitoring directly on a machine-mounted operator terminal
- Driving auxiliary control relays, visual indicator stacks, and 24 VDC industrial solenoids
- Integrating remote skid automation without adding a secondary networked remote I/O rack
- Upgrading benchtop test fixtures and shop automation cells using surplus host hardware
Frequently Asked Questions
How are the input logic types and input filters configured on the GMDIOS?
Input logic (sinking or sourcing) and hardware filtering are set individually per channel using the dedicated dual 8-position DIP switch blocks located on the side panel of the module.
Does this module require an external 24 VDC power supply connection for logic operation?
Internal logic power is supplied directly from the host backplane, drawing up to 3.6 W maximum. Field outputs switch external load power up to 30 VDC at 1 A per point.
What terminals connect field wiring to this module?
Wiring lands on three front-facing 6-position removable screw terminal blocks numbered 1 through 18, which are installed on the unit.
What host hardware does this expansion module mate with?
This module plugs directly into the expansion backplane slots on Red Lion Graphite series operator interface panels.
Industrial automation moves fast, but steady I/O hardware keeps machines turning out parts shift after shift. Seat this module into your backplane and put those extra control lines to work.
