Data Line Protection
ACS Series
Amber's Card System (ACS) is a data line transient voltage suppressor system that can be mounted either inside or outside your equipment. Each ACS is composed of Motherboards and Suppressor Cards and will protect up to 20 or 32 data or transducer lines in control or monitoring circuits.
The ACS Series suppresses positive and negative transients. The units in this series have two stage protection and nanosecond response times. Also, they have terminal strips for easy installation and connectors for ease of service.
The units in the ACS Series are data line suppressors in a daughter and motherboard format. There are four wires per card, with up to 8 cards per motherboard.
Daughterboard Data Line Protection with Four Wires Each
The ACS-12, 25, & 50 cards are intended for use on data or transducer line voltages of less than +/-12Vpk, +/-25Vpk and +/-50Vpk respectively. The ACS-12 cards are generally used on RS-422, 423, and 485 lines, while the ACS-25 cards are generally used on RS-232 lines. For 4-20 ma loops it may be appropriate to use any of these cards depending upon the loop power supply rating or open circuit voltage. The ACS-175 is intended for use on telephone lines which may have a ring voltage present.

Motherboard Data Line Protection for Up to Thirty-two Wires
The wiring interface consists of a "Motherboard" with either five (5) or eight (8) card edge connectors for use with the suppressor cards listed above. The edge connectors, screw-type terminal strips, and two ground studs allow for ease of installation. Keying of the motherboard and the suppressor cards maintain isolation between the transient side and the protected side on the motherboard. The I/O screw terminal strips are labeled from 1 to 20 or 1 to 32 depending on the motherboard chosen. The suppressor cards may be mixed, therefore, providing different clamp voltages or the same clamp voltage depending upon application requirements. Nema types 1, 12, and 4 enclosures are available as options.
