The JB220 standard size, premium stainless steel switch box is used to convert the three-conductor input wiring of up to 12 remotely installed dual-output accelerometers or piezo velocity sensors to two switched BNC's and a switched three-pin MIL spec connector for data collection. JB Series enclosures are designed to have field input cabling installed behind the board. A flip-down panel allows the user to wire connections on location. The shield drain wire is earth grounded via the stainless steel enclosure. Each terminal block includes inputs for signal, temperature, negative and shield. The shield drain wire is earth grounded via the stainless steel enclosure. Additionally, the JB Series can be equipped with online expansion terminal strips, which can be selected upon ordering. The JB Series also features an IEPE bias indicator light built into the box itself, which can be used to indicate errors in the field wiring of the sensor.

Rated for NEMA 4X (IP66), the JB220 can withstand harsh environments including temperatures ranging from -58 to 180 °F (-50 to 82 °C). The box is also resistant to hose directed fluid and corrosion.
