Larson Electronics Isolation Barrier for Explosion Proof Phone - 90-132V or 180-240V

The Larson Electronics Isolation Barrier is designed to support explosion proof phones with the following NEC ratings: Class I, Groups A, B, C, D; Class II, Groups E, F, G and Class III. This unit features 90-132V and 180-240V @ 47-63 Hz AC power input options. During installation the component is to be placed in a non-hazardous location up to one mile from the explosion proof phone. The isolation barrier may be used to meet intrinsically-safe requirements and regulations by limiting energy levels entering the hazardous area. It is constructed of glass-reinforced polyester with Type 3R (rainproof) ratings. Features: The Isolation Barrier supports 90-132V and 180-240V @ 47-63 Hz AC power input options. While the Intrinsically Safe Interface (ISI) features a maximum voltage of eight volts, 66 ohms resistance and 136 mA current limited. The unit is compatible with 2-wire (BELL Pub.61100) and 4-wire telephone network interfaces. This component is to be installed in a non-hazardous area of the location up to one mile from the explosion proof communication device. The Isolation Barrier interior comes with a power switch selector, a ring pitch adjustment, and four troubleshooting LEDs. Externally, the component consists of two modular subassemblies, the front panel and the rear enclosure assembly, for easy installation and wiring. Operators may adjust the pitch of the ring between 1 kHz and 8 kHz. This device operates in temperatures ranging between -40¡C and 60¡C with 95 percent (non-condensing) relative humidity. The Isolation Barrier supports a glass-reinforced polyester body, which is Type 3R rated, making it highly resistant to rain, weather and chemicals. There are four indicators on the unit that notifies operators about a wiring short in the IS phone and if the TELCO line has an open. In the event of an intermittent wiring short in the IS phone, the notification lights will flash. The Isolation Barrier features twisted pair (shielded) wiring with a wiring conductor size of 24 AWG. This component’s wiring loop resistance is 275 ohms with a wiring capacitance of 0.316 uF. Installation: The unit must be wired in accordance with Pub. 42004-380, Control Drawing 73242, to ensure intrinsic safety. Telephone system wire must be connected to the Isolation Barrier Unit only and not directly to the IS communication device. Shielded cables must be used when multiple IS telephone wires are routed together to prevent cross-talk. The shield must be grounded to an IS ground and connected only at the Isolation Barrier. There are four mounting holes (0.280-inch diameter) on this unit. At Larson Electronics, we do more than meet your lighting needs.
