8 Form C Relay Output / 8 Isolated Input Digital Interface Price & Specs
Sealevel Systems PLC-16.PCI 8 Form C Relay Output / 8 Isolated Input Digital Interface Description
Functions
Provides 8 Form C relay outputs for switching external devices and 8 isolated digital inputs for sensing external signals. Operates in a PCI bus environment. Relay outputs feature Normally Open (NO), Normally Closed (NC), and Common (COM) terminals. Isolated inputs protect the host system from voltage spikes and ground loops.
Platforms
A PCI bus expansion card for PC-based control and automation. Provides eight Form C electromechanical relays for switching AC/DC loads and eight optically isolated, non-polarized inputs for sensing contact closures or DC voltage from 3-30V. External connections are made via a DB-78 connector. Ideal for industrial I/O, data acquisition, and interfacing with external sensors, switches, and control devices, protecting the host computer from transient voltage spikes and ground loops.
Applications
Designed for process control applications, this digital interface provides eight Form C (SPDT) relay outputs capable of switching up to 60W and eight optically isolated inputs supporting 5-30V DC signals. The PCI card integrates with industrial control systems, enabling communication between computers and external devices like motors, valves, switches, and sensors. It features user-configurable contact closure, programmable input filtering, and comprehensive driver support. Applications include automated manufacturing, environmental monitoring, test/measurement systems, facility management, and scientific data acquisition where reliable switching and isolation between digital systems and higher-voltage field devices are required.
Accessories
Requires a standard PCI slot in a compatible computer or industrial controller. Features 8 Form C (SPDT) relay outputs capable of switching up to 3A at 30VDC/125VAC, and 8 optically isolated inputs rated for 3-30VDC (sourcing or sinking). Connects via DB37 male connector on board bracket. Compatible with standard 37-pin D-sub cables. Optional DIN rail mount terminal blocks available for field wiring. Supports Windows and Linux operating systems. Operates from PC power with no external power required. Includes SeaMAX API software for programming.
Interfaces
PCI bus connector 32-bit 5V compatible, 16 isolated digital inputs with optocoupler isolation 5000V, 8 Form C relay outputs rated 2A at 30VDC or 250VAC, DB-37 female connector for field wiring, requires PCI slot in host computer, field connections via screw terminal blocks on DB-37 breakout cable, status LEDs for input and relay states
Specifications
Provides 8 Form C relay outputs and 8 optically isolated digital inputs designed for PCI bus interface. The Form C relays allow single-pole double-throw switching for versatile control of AC/DC loads. Inputs are isolated to protect host systems from voltage spikes and ground loops. The device supports industrial I/O voltage levels, interfacing directly with sensors and control equipment. Fits standard PCI slots and integrates with PC-based control and monitoring systems. Commonly used in industrial automation, test instrumentation, and equipment control requiring reliable relay-based output and isolated digital input sensing.

We found Artisan when our PXI Chassis broke, which shut down our production line. We were up and running in less than a day because they shipped overnight and talked our tech guys through the installation over the phone. ATG saved the day big time!
