Honeywell 10206/2/1 Digital Output Module

The Honeywell 10206/2/1 is a digital output module specified for industrial automation and process control applications. It provides 12 output channels for controlling external devices, with a stated 24 VDC operating level and a current rating of 0.55 A per channel. The supplied specifications identify resistive loads, such as lamps, and inductive loads, such as solenoids, as supported load types.

Output Configuration

The 12-channel configuration allows the module to control multiple discrete output points. Each channel is rated at 0.55 A, with a stated load capacity of up to 13 W per channel. Actual load selection must account for the connected device's voltage and current requirements, particularly the inrush current and switching characteristics of inductive loads.

Technical Specifications

Output Grouping and Load Protection

The module divides its 12 outputs into two groups of six, each with a separate external 24 VDC supply connection. This arrangement allows the two output groups to use independent power supplies, supporting power segregation or separate circuit protection. Each output is a solid-state source output with short-circuit protection.

A built-in suppression diode on each output limits inductive voltage transients when loads such as solenoids are switched off. The module also uses watchdog control to de-energize outputs when the system shuts down and the watchdog switches them off. However, the outputs are not tested for fail-safe applications and should not be selected as fail-safe outputs.

Power and System Requirements

The published hardware specifications list internal power requirements of 5 VDC at 25 mA and external 24 VDC at 230 mA without output loads. The external load supply must also account for the current drawn by connected devices. Check the installed module version and applicable hardware documentation before finalizing power-supply sizing.

Frequently Asked Questions

Q: Can the Honeywell 10206/2/1 be used for fail-safe output control?

A: No. The module's outputs are not tested for fail-safe applications. A safety-related output function requires a module specifically approved and configured for that purpose.

Q: How are the 12 output channels powered?

A: The channels are divided into two groups of six, with separate external 24 VDC supply connections for the two groups. This permits independent field-power distribution between the groups.Q: What protection is provided for inductive loads?

A: Each output includes a suppression diode to limit inductive voltage transients. The connected load must still remain within the module's specified current and power limits.
