Omron G70a-zoc16-4 Output Module

What is an Omron G70A‑ZOC16‑4 Output Module?

The Omron G70A-ZOC16-4 is a 16-point output terminal base (socket), to be used with Omron’s G70A I/O block system. This output base provides the interface between control wiring and relays or solid-state relays for output circuits. The official Omron specification for the model code “ZOC16-4” denotes an output base of PNP (– common) polarity with 16 output points.

In essence, this module forms an important part of modular I/O systems in industrial automation as it simplifies wiring, allows flexible relay/SSR mounting, and supports quick connection to power supply and I/O modules.

Key Features

Following are the key features and specifications that distinguish this G70A-ZOC16-4 module:

1. 16-Point Output Base

One module supports 16 output channels (16 positions).

Designed for PNP polarity (– common), meaning the common return is negative.

2. Relay/SSR Wiring Interface

Terminal type: Relay wiring interface (screw terminal)

Allows the mounting of relays or SSRs on the block base, allowing for flexibility in choosing an output device.

3. DIN-Rail & Modular Mounting

The socket is designed for DIN-rail mounting to allow for easy integration into standard industrial panels.

The G70A series enables modular stacking and expanding of I/O using connector systems.

4. Electrical and Insulation Ratings

Dielectric strength: 4,000 VAC between connector and output terminals; 2,000 VAC between output terminals.

Insulation resistance: 1,000 MΩ minimum between connector and I/O terminals (at 500 V) in some models.

Permissible current: Up to 10 A for the outputs, when used properly, according to the datasheet for a similar model.

5. Reduced Wiring & Enhanced Safety

The modular base reduces the number of individual terminal blocks required while simplifying wiring layout in control cabinets.

Finger-touch protective terminal block incorporated to meet safety standards such as VDE 0160, etc. in the G70A family.

6. Clear Connection Polarity & Wiring Method

The module uses screw terminals for wiring (robust for industrial use).

Power supply wiring: A 24 VDC supply is commonly used for the module and outputs, typically. For example, as in the DC24 version of the product.

Applications

Due to its modularity and output capacity, the G70A-ZOC16-4 is suitable for a wide array of industrial automation applications. Typical uses of this unit include the following:

Control Panels & Machine Automation: Used in manufacturing lines, packaging machines, conveyors etc. where multiple output channels (actuators, lamps, solenoids) are required.

Building Management Systems (BMS): Where the centralized I/O modules manage alarms, indicators, HVAC control outputs.

OEM Machine Builders: OEMs can use this base in their I/O architecture for modular design, ease of expansion, and reduced wiring complexity.

Marine & Offshore Automation: With your focus being industrial and marine automation parts, this module could be used for control panels onboard ships or offshore rigs where reliable, modular output terminals are required.

Retrofit/Maintenance Projects: When older systems are being modernized, a modular output block of this nature assists in the integration of modern relays/SSRs with much easier wiring and replacement.

In all cases, the 16-point form and compatibility with relay/SSR options mean that you can support a high quantity of outputs in compact format.

Why choose this module?

The selection of G70A-ZOC16-4 provides a number of advantages for listings on industrial & marine automation products, particularly for your website and store at Aeliya Marine Tech. Here’s why:

Reliability & Proven Brand

Omron is a reputable global brand in industrial automation, offering high-quality I/O systems. Using a known brand increases buyer confidence.

The G70A series has strong insulation and durability ratings, up to 4,000 VAC dielectric strength, which means it’s built for industrial use and challenging environments.

Flexibility & Scalability

With one base containing 16 output points, you can support many outputs in one module for efficient panel layout.

Compatibility with relays or SSRs provides flexibility depending on your output requirements (AC or DC loads, high power, etc.).

Modular DIN-rail design helps in future expansions or changes in the field.

Wiring Efficiency & Cost Savings

It reduces wiring complexity compared with using individual terminal blocks for each output channel.

Screw-terminal interface and finger-touch protection enhance safety and facilitate the installation/maintenance process.

Modularity means less installation and service time, which is great for both OEMs and service teams.

Ideal for Marine & Industrial Environments
