APC by Schneider Electric Easy UPS 3S DRY Contact Card - E3SOPT010

APC by Schneider Electric E3SOPT010 Dry Contact Relay Card

Overview

The E3SOPT010 is an optional dry contact card designed to extend the signaling capabilities of APC by Schneider Electric Easy UPS 3S systems. Dry contact relay outputs give building management systems, generator controllers, and third-party monitoring platforms a hardware-level signal path — independent of network or software — to act on UPS status events like on-battery, low battery, or fault conditions. If your UPS installation needs reliable, protocol-agnostic alarm integration into a BMS or facility automation system, the E3SOPT010 is the card that enables it.

Key Features

• Dry Contact Output: Relay contacts carry no voltage of their own, so they integrate cleanly into virtually any BMS or generator control input without ground-loop or voltage-mismatch concerns — no isolation transformer needed on the monitoring side.
• Compact Add-In Form Factor (60 × 68 × 12 mm): At roughly credit-card width and shallower than a standard option slot, the card installs without consuming adjacent bays or requiring chassis modifications on compatible Easy UPS 3S units.
• Single-Unit Pack: Sold as a single card per pack — order exactly the quantity your installation requires without over-purchasing bundled accessories.
• Targeted Compatibility: Engineered for the Easy UPS 3S 208V and Easy UPS 3S Pro 400V families. Installing in an unsupported chassis voids the expected signaling behavior, so confirm your UPS option slot matches before ordering.

Integration & Compatibility

The E3SOPT010 is verified compatible with the Easy UPS 3S 208V and Easy UPS 3S Pro 400V platforms. Facilities running a centralized power monitoring or DCIM solution will wire the dry contact outputs to the monitoring system's digital input terminals. Because the relay is potential-free, it accepts the monitoring system's own wetting voltage, making integration straightforward across diverse BMS brands and vintages. Verify the number of available option slots in your specific chassis before ordering additional option cards.

Frequently Asked Questions

Q: Which UPS models is the E3SOPT010 compatible with?

A: The E3SOPT010 is compatible with the APC Easy UPS 3S 208V and the APC Easy UPS 3S Pro 400V. It is not verified for other Easy UPS families or legacy Smart-UPS platforms.

Q: What are the physical dimensions of the E3SOPT010?

A: The card measures 60 mm wide × 68 mm deep × 12 mm tall, making it a compact single-slot option card for the supported Easy UPS 3S chassis.

Q: What is a dry contact relay and why does it matter for UPS integration?

A: A dry contact relay is a potential-free switching output — it contains no voltage on its own. This means you can wire it directly into a BMS, generator controller, or alarm panel input regardless of that system's wetting voltage, without risking ground loops or requiring isolation hardware.

Q: How many E3SOPT010 cards come in a single order?

A: One card per pack. Order the quantity that matches the number of UPS units requiring dry contact output capability.

Q: Can the E3SOPT010 replace a network management card for SNMP monitoring?

A: No. The E3SOPT010 provides hardware-level dry contact relay outputs only — it does not support SNMP, Modbus, or any network protocol. For IP-based monitoring, a separate network management card is required.
