Product Overview

The GE Fanuc IC695CRH003 is a harness assembly. It belongs to the RX3i PacSystems series. This assembly connects Series 90-70 MDL250 devices to RX3i MDL260 modules.

The harness enables migration from legacy 90-70 I/O to modern RX3i systems. Therefore, it preserves existing field wiring while upgrading the controller platform.

Compatible Modules

The IC695CRH003 works with two specific GE Fanuc modules.

IC697MDL250 (Series 90-70):

• 120 Volts AC input module.

• Provides 32 input points for the programmable controller.

• 32 inputs divided into 4 groups (8 input points per group).

• Reactive inputs with IEC-compliant current-voltage characteristics.

• Compatible with a wide range of proximity switches.

• LED indicators display on/off status of each input point.

• Power consumption: 0.35 Amps at 5 Volts DC.

IC694MDL260 (RX3i):

• RX3i PacSystems input module.

• Individual input groups are isolated.

• All input circuits within the same group share a common user connection.

• Input filter times configurable through a programmer.

Group Isolation and Configuration

The IC695CRH003 enables specific isolation characteristics.

• Group Division: 4 groups with 8 input points each.

• Per-Group Isolation: Each group can use a separate phase of the AC supply.

• Within-Group Common: All inputs in the same group share a common user connection.

Hence, the harness preserves the isolation and grouping of the original 90-70 MDL250 configuration.

Input Electrical Characteristics (IC694MDL260)

When used with the IC695CRH003, the MDL260 exhibits specific input characteristics.

• Off-State Voltage Range: 0 to 20 Volts AC.

• On-State Current (minimum): 5 milliamps.

• Off-State Current (maximum): 2.5 milliamps.

Therefore, the MDL260 reliably detects AC input signals within these parameters.

Power Consumption

The IC695CRH003 and its host modules have defined power requirements.

• IC697MDL250: 0.35 Amps at 5 Volts DC.

• IC694MDL260 (with harness, all inputs on): 220 milliamps at 5 Volts DC.

Consequently, ensure your RX3i power supply can accommodate these loads.

Configuration Flexibility

The IC695CRH003 allows programmer configuration of input filter times.

• Configurable Parameter: Input filter times.

• Configuration Method: Through a programmer.

• Applicable Module: IC694MDL260.

Thus, filter settings can be adjusted to match specific field device response requirements.

VME Standard Compliance

The entire system of the IC695CRH003 harness assembly and its host modules meets VME standard C.1. Therefore, it complies with established mechanical and electrical specifications for VME-based systems.

Key Features

The IC695CRH003 offers several advantages for system migration.

Legacy to Modern Migration:
Connects Series 90-70 MDL250 to RX3i MDL260 devices. Consequently, field wiring can be reused while upgrading the PLC platform.

32 Input Points in 4 Groups:
Provides 32 AC input points divided into 4 groups of 8. Hence, each group can operate on a different AC phase.

Configurable Input Filtering:
Input filter times are programmable via a programmer. For this reason, the system adapts to different field device response characteristics.

VME Standard C.1 Compliance:
Meets VME standard C.1 mechanical and electrical specifications. Therefore, it integrates reliably into VME-based systems.

LED Status Indication (on MDL250):
Individual LEDs show the on/off status of each input point. Thus, troubleshooting is simplified.

Reactive Inputs (on MDL250):
Inputs are reactive with IEC-compliant characteristics. Consequently, they work with a wide range of proximity switches.

Typical Applications

The IC695CRH003 suits various migration and interconnection applications.

• Upgrading Series 90-70 PLCs to RX3i PacSystems while retaining field wiring.

• Interfacing 120 VAC input devices to RX3i MDL260 modules.

• Migrating legacy 32-point AC input groups to modern RX3i platforms.

• Retrofitting existing 90-70 I/O installations.

• System expansions requiring harnessed connections between 90-70 and RX3i components.

Installation Guidelines

Install the IC695CRH003 between a Series 90-70 MDL250 and an RX3i MDL260 module. First, ensure both modules are properly mounted in their respective racks. Then, connect the harness assembly to both modules securely.

Verify that the voltage rating (120 VAC) matches the field input voltage. Configure input filter times on the MDL260 through a programmer as required. Each of the 4 groups can be used with a separate phase of the AC supply.

Power consumption for the MDL260 with the harness is 220 mA at 5 VDC (all inputs on). The MDL250 consumes 0.35 A at 5 VDC. Therefore, verify total load on the power supply.
