IC693MDL940 24VDC/240VAC Output Module GE

Product Overview

The GE Fanuc IC693MDL940 is a high-performance relay output module designed for the Series 90-30 Programmable Logic Controller. It provides 16 discrete outputs, arranged in four isolated groups of four, allowing for the switching of different voltage sources within a single module. With a net weight of 0.4 kg (0.88 lbs), this unit offers a compact yet powerful interface for high-current industrial loads. It is engineered to handle both AC and DC voltages, making it a versatile choice for applications requiring mechanical contact isolation and high current-carrying capacity.

Core Technical Advantages

The IC693MDL940 is built for heavy-duty operation, supporting a maximum load of 2 Amps per output and a total module capacity of 16 Amps. This 0.4 kg module features a rapid response time of 15 ms for both "on" and "off" cycles, ensuring timely execution of control logic. To protect sensitive backplane electronics, the module provides 1500 VAC isolation for one minute between the field side and the logic side. Additionally, with its low power draw of only 7 mA from the 5V bus, it minimizes the thermal load on the PLC power supply even when all 16 relays are energized.

Installation & Wiring Guidelines

When installing the GE Fanuc IC693MDL940, ensure the PLC rack power is disconnected before insertion. The 0.4 kg unit fits into any I/O slot of the Series 90-30 baseplate. Because the module can switch up to 250 VAC, users must adhere to local wiring codes, particularly regarding point-to-point isolation. The module supports a maximum common load of 4 Amps per group. It is recommended to use surge suppression (such as MOV or RC snubbers) when driving inductive loads to extend the mechanical life of the relay contacts and prevent EMI interference with adjacent modules.

Engineering Advantages

Engineers prefer the IC693MDL940 for its high-density relay count, which significantly reduces the number of modules required for large-scale output control. The mechanical relay design eliminates the leakage current issues found in Triac or Transistor modules, providing a "true open" state that is safer for certain maintenance procedures. Despite its 0.4 kg physical profile, the module is exceptionally rugged, capable of handling inrush currents up to 5 Amps. Its ability to switch mixed loads (AC and DC) within different groups makes it an incredibly flexible tool for modernizing legacy control systems.

Technical FAQs

Q1: What is the weight of the GE Fanuc IC693MDL940?
A1: This module has a net weight of 0.4 kg (0.88 lbs), reflecting its robust internal relay array and protective housing.

Q2: What is the minimum load requirement for the relays?
A2: To ensure reliable contact closing and prevent oxidation buildup, a minimum load of 10 mA is required for each output point.

Q3: Does the IC693MDL940 require an external power source?
A3: Yes, while the logic side is powered by the backplane, the relay coils require 135 mA from the 24V bus (typically provided by the PLC power supply) when all outputs are energized.
