TSXDSY16R5 Schneider Electric 16-Point Relay Output Module

Product Overview: TSXDSY16R5 Discrete Output Module

The Schneider Electric TSXDSY16R5 is a 16-point discrete output module from the Modicon Premium series. It uses electromechanical relay outputs to switch both DC and AC field devices. Because each channel is normally open and isolated from the backplane, the module suits mixed-voltage control panels. This buyer's guide explains the exact specifications you should verify before selecting the TSXDSY16R5 for your application.

Key Specifications of the TSXDSY16R5

• Channels: 16 points arranged in 2 groups of 8.
• Signal type: Relay output, normally open, electromechanical.
• Voltage range: 24 V DC to 250 V AC.
• Output current: 3 A per channel conventional thermal; 5 A max at 250 V AC / 30 V DC.
• Isolation: Channel-to-bus 1500 V AC dielectric; isolation resistance above 10 MΩ at 500 V.
• Response time: Under 8 ms activation, under 10 ms deactivation.
• Supply voltage: 24 V DC field and 5 V DC backplane.
• Bus current: 80 mA at 5 V DC.
• Power consumption: 0.25 W plus 0.2 W per output at state 1.
• Protection rating: IP20.
• Dimensions (H×W×D): 140 × 35 × 80 mm.
• Weight: 0.25 kg.
• Slots required: 1.

Relay Output Architecture and Isolation

Each of the 16 outputs is an electromechanical relay contact. Consequently, the TSXDSY16R5 can directly switch loads that draw up to 3 A continuously. The 1500 V AC channel-to-bus isolation protects the backplane from field transients. In addition, isolation resistance exceeds 10 MΩ at 500 V, which limits leakage between channels and the bus. However, the module has no built-in diagnostics. Therefore, an external fuse is required per channel or group to protect the relay contacts from overcurrent.

Buyer's Checklist: Matching the TSXDSY16R5 to Your Application

Before ordering, confirm three parameters. First, verify that your field voltages fall within 24 V DC to 250 V AC. Second, calculate the total current per channel; the 3 A conventional thermal rating and 5 A maximum apply at 250 V AC / 30 V DC. Third, check the response time requirement: under 8 ms activation and under 10 ms deactivation may not suit high-speed sorting or registration tasks. Also, remember that each channel needs an external fuse because the module provides no built-in diagnostics.

Installation and Environmental Considerations

The TSXDSY16R5 occupies one slot in a Modicon Premium rack. It draws 80 mA from the 5 V DC backplane and requires a 24 V DC field supply. The IP20 rating means the module must be mounted inside a clean, protected enclosure. Because operating temperature, storage temperature, and relative humidity are not available in the source data, refer to the official datasheet for those environmental limits. Please verify current lifecycle status and availability with AutoDCSTech before ordering, as this module is discontinued.
