A new family of 6mm wide, DIN rail mount, signal conditioning and relay modules are available from WAGO Corporation. Designated the 857 Series, aka JUMPFLEX, the new modules offer a system approach to signal switching and conditioning.
"Today's factory automation and process control applications require conversion, isolation, and transmission of many different signal types. With these requirements comes the challenge of managing signal types, maximizing panel space, reducing signal wiring and downtime, while controlling overall signal costs," explained Dean Norton, Marketing Manager for WAGO Corporation. "The new 857 Series signal conditioners and relays meet this challenge and more."
The System
Housed in a "true" 6mm wide package, the signal conditioning and relay modules also offer the same dimensional outline. In addition to good aesthetics in the control cabinet, a common profile allows the sharing of accessories, such as jumpers (every wire entry has a corresponding jumper slot). The modules push-in jumper system, available in red, white and blue color designations and 2 to 10 poles, facilitates both time and cost savings. An example being, commoning of the 0V potential for a group of relays and signal conditioners thereby eliminating the need for additional wiring.
Further system features include; pre-marked modules for easy circuit identification, marking tag holder for module identification, built-in indication for power or signal status, and CAGE CLAMPÒS wiring technology for fast, easy and maintenance-free wiring.
Signal Conditioners
The 857 Series signal conditioners consist of 12 different modules, both configurable and dedicated modules are available. Signal types supported include current, voltage, Hart protocol, RTDs and thermocouples. Configurations include splitter, single and multi-channel, repeater, as well as loop powered modules. The configurable modules are programmed via dipswitch (for current, voltage, and temperature) and/or FDT/DTM software (temperature only). For example, the 857-400 (configurable isolation amplifier) offers up to 36 different signal combinations via dipswitch.
Additional features include; safe operation with 3-way isolation (2.5kV), accurate signal transmission with error <0.1% of full scale value, built-in potentiometer for zero and span adjustment, extended operating temperature range of –25 to +70 degrees Celsius, as well as worldwide approvals including UL 508, CSA 22.2, and UL 1604 (pending).
Relay Modules
The 857 Series relay modules includes a growing line of pluggable relay types. Up to 7 different modules offer a wide variety of AC/DC coil voltages and are capable of switching loads up to 250V and 5A. Pre-marked wiring points, as well as mechanical separation of the coil and load side, provide for safe wiring. The relay modules are currently being testing to UL 508, CSA 22.2, and UL 1604.
