Mini-FRI Field Rely Interface From Jack Fuse Converts DC Voltage For Dry Contacts.

Mini-FRI Field Rely Interface From Jack Fuse – Mini-FRI field relay interface from Jack Fuse is a miniature low power relay for interface to security and other equipment that converts a DC voltage signal to a single pole double throw dry contact that’s ideal for inline connections and tight spaces.

“The Mini-FRI interface relay is perfect for most security and EACS interface requirements,” says Jack Fuse’s Ken Mckeon. “It requires a simple 2-wire DC voltage for operation and its miniature size allows it to be installed into tight spaces, such as door frames, behind switch plates and inside automatic door/gate controllers without using fixings or DIN rail.

“An on-board LED indicator allows the relay status to be identified without needing to use a multi-meter. Spring clamp terminals are used to secure the connecting wires. Unlike screw terminals that can loosen with movement and changes in temperature, the Mini-FRI terminals maintain a constant pressure on the conductors over the life of the connection. The terminals can also be operated by hand

reducing the number of tools required and increasing installation/repair efficiency.

Low drop out and pick up voltages allow the Mini-FRI relay to keep working even when there is a significant voltage drop due to long cables or a failing power supply. For example, the Mini-FRI-12 will work as intended at 8VDC or 5.6V below a typical security power supply voltage rating.

Reverse polarity and inductive kick back (sometimes called back EMF) protection is included onboard eliminating the need to add external diodes and reducing the chance of damage to the Mini-FRI and upstream devices.

Functionally, Mini-FRI is installed in-line with security cabling and the relay coil is powered via the terminals marked + and – and installers apply a DC voltage to energise the relay. An energised relay is indicated by an illuminated green LED. The Mini-FRI has both reverse polarity and energy spike protection diodes on board.

A single pole double throw (SPDT) also known as a 1 Form C configuration is used for the relay contacts. The relay contact terminals are marked NC, C and NO. The normally closed (NC) contact is closed and connected to the common (C) terminal when the Mini-FRI is unpowered. Once power is supplied this contact changes over and the normally open (NO) contact is then connected to the common terminal.
