PLCs, Power Supplies & Others

The Honeywell 620-0088 parallel link drive module handles high-speed data transfer between controllers. This unit weighs 0.48 kg and measures 15.5 cm x 9.8 cm x 3.5 cm. It provides two 36-pin Centronics-style connectors for parallel communication. The module contains four line driver ICs and two receiver ICs. For energy storage, it includes two 220µF electrolytic capacitors. Consequently, the Honeywell 620-0088 maintains data transmission during brief power interruptions.

Technical Specifications

The table below lists all verified parameters for the Honeywell 620-0088. Use this data for your system integration planning.

Parallel Communication Features

The Honeywell 620-0088 uses four line driver ICs for robust signal transmission. These drivers convert TTL signals into high-current outputs. Therefore, the module drives cable lengths up to 15 meters reliably. The two receiver ICs accept incoming data from remote devices. Consequently, this module supports bidirectional parallel communication between controllers.

Data Transfer Performance

This parallel link module achieves transfer rates up to 2 MB per second. Thus, it suits high-speed data exchange between PLCs and remote racks. The Honeywell 620-0088 uses standard 5V TTL signal levels for compatibility. Hence, you can connect it to most industrial controllers without level converters. The timing controller manages handshaking signals automatically.

Power and Energy Storage

The Honeywell 620-0088 draws 300 mA from a 5V DC supply. Hence, its total power consumption equals just 1.5W. The two 220µF electrolytic capacitors provide 10 milliseconds of hold-up time. This short backup protects data during minor voltage sags. Furthermore, the module generates very little heat during operation.

Installation and Connectivity

You can mount the Honeywell 620-0088 on a standard DIN rail. Alternatively, secure it with M4 screws through its four mounting holes. The two 36-pin Centronics connectors accept standard parallel printer cables. For best performance, use shielded cables with proper grounding. Keep these cables away from high-voltage power lines. The Honeywell 620-0088 works seamlessly with the RMS-TSG-TZ-C static trip unit.

Environmental Durability

This parallel link drive module operates reliably from 0°C to +55°C. It also withstands 90% relative humidity without condensation. The module survives vibration up to 2g from 10 to 150 Hz. Therefore, the Honeywell 620-0088 suits most industrial control rooms perfectly.
