The GE Druck UPS-II can power (24 Vdc) and read 2-wire transmitters to perform field calibrations. Output currents are adjustable to a resolution of 10 microamps in both source and transmitter simulation modes. (read more)

MCG Surge Protection of Deer Park, NY recently introduced data line protection designed to guard critical control circuits from lightning-induced transients. The UL-listed DLP-25 series comes in three offerings – light duty, standard duty, and heavy duty and protects up to five wires. The DLP-25 uses a compact aluminum DIN rail mount enclosure. Also mounts on flat surface. (read more)

The UL-listed DLP-36B is a 25 pair (50 wire) data line transient suppressor offering high speed protection for PABX systems, key systems, port selectors and any instrumentation systems using telephone lines, RS-232, 423 and 20 mA loops. (read more)

The UL-Listed DLP-10G, DLP-20G and DLP-30G combine brute force gas tube protection with high-speed avalanche diode stages for rigorous transient clamping. Protects 2-8 wires. Hard-wire installation offers universal capability. (read more)

The 500 Series protects 12, 16, 24 or 32 sensitive RJ45 ports (each port has 8 protected wires) against transient/surge damage right at the critical HUB location. Incoming network cables are routed through the MCG protector prior to their entry into the HUB's sensitive I/O ports. (read more)

DLP-5.10 protects 10BASE-T, HUB's, routers, token ring and I/O ports. Installation of the compact unit (6.4" x 2.06" x 1.05") is quick and easy (less than 5 minutes) using BNC connectors. Clamp voltage is 6V; series resistance is 2 Ohms. Center and shield lines are protected. (read more)
