Product Introduction
When upgrading aging discrete I/O systems, the GE IC200MDD845 mixed module offers a reliable solution. Part of the VersaMax I/O family by Emerson Automation, this module combines 16 positive-logic 24 VDC inputs with 8 individually isolated Form A relay outputs rated at 2.0 Amperes. The module draws a maximum backplane current of 270 mA, making it efficient for distributed I/O stations or native VersaMax control systems. Each channel features individual LED indicators plus an OK LED to monitor backplane power.
Technical Specifications Breakdown
The GE IC200MDD845 delivers precise performance parameters. Key specifications from the datasheet include:
| Parameter |
Value |
| Input voltage (nominal) |
24 VDC |
| Input voltage range |
18–30 VDC |
| On-state current |
2.0–5.5 mA |
| Off-state current |
0–0.5 mA |
| Output type |
8 Form A relay contacts, individually isolated |
| Output voltage range |
0–125 VDC, 0–265 VAC (47–63 Hz) |
| Contact rating (resistive) |
10 mA min; 2.0 A at 5–265 VAC; 2.0 A at 5–30 VDC; 0.2 A at 31–125 VDC |
| Backplane current consumption |
270 mA max |
| Dimensions (H x W x D) |
110 mm x 66.8 mm x 50 mm |
These values ensure the IC200MDD845 handles both low-voltage DC sensors and higher-power AC loads, with output channels isolated for safety.
Industry Applications
The GE IC200MDD845 fits numerous automation tasks. In packaging lines, its 24 VDC inputs read proximity sensors while relay outputs control solenoids or small motors. For material handling, the module monitors conveyor status and drives alarm indicators. Because the outputs support up to 265 VAC, it can switch pilot lights, contactors, or valve actuators directly. When replacing older 16-point input or 8-point output modules, this mixed unit reduces panel space and wiring.
Installation & Setup Guidance
Mount the GE IC200MDD845 on a compatible VersaMax carrier base (IC200CHS series). Ensure backplane power is off before insertion. Wire positive-logic inputs with a common supply return; for relay outputs, connect loads across the Form A contacts (normally open). The module does not include internal fuses or snubbers—add external protection for inductive loads. After installation, verify the OK LED lights to confirm backplane communication. Channel LEDs indicate individual I/O states, aiding quick commissioning.
Selection Guide & Purchasing Advice
Before ordering a GE IC200MDD845, confirm your system’s backplane current budget (270 mA max per module) and the required number of I/O points. This module replaces or supplements older discrete I/O racks. For additional support, contact UBEST Automation, your trusted source for industrial automation parts.
