AR-2MF USB RELAY

The AR-2MF Multi-Function USB Relay is a stand alone relay interface for connection to USB which provides software control of (2) relays which are included and mounted on the AR-2 circuit assembly. The relays are energized or de-energized by using the RS-232 control signals DTR and RTS or alternate relay control setting (set by shunts on the circuit board). When the alternate relay control is selected, DTR and RTS no longer control the relays and the relays are controlled using relay control commands. The AR-2MF can be used as a direct replacement for the AR-2 when connected to USB with no software changes needed (Windows 2000/XP/Vista/Windows 7/8.1, Windows 10 and Windows 11, Windows Server). The AR-2MF is for use with USB only using a standard USB cable (or OTG cable for Android devices with a micro USB port). The EN-C Instrument Case may be used to house the AR-2MF if an enclosure is required. The relays are SPDT rated at 16 amp 250 volts AC. A terminal block is provided for relay contact connections (12 to 30 awg wire size using rising cage clamp design). Power is supplied to the AR-2MF through the USB connection. USB connection is via a USB type B receptacle (CC-USBB1 or CC-USBB6 connector cable required). Software and source code examples are provided that allow the AR-2MF relays to be controlled from your desktop, your program or controlled over a network (LAN, Wi-Fi, Internet, etc.). The AR-2MF is Android device compatible (free apps on Google Play and our web site). The AR-2MF may be ordered with an optional expansion port that will allow the AR-2MF to be expanded up to a total of 10 relays (or 8 inputs or combinations) using the EX-8M Expansion Card. Relays may be time scheduled using the SW-A Load Programmer software for 7 day time control of relays. LabVIEW compatible, includes LabVIEW VI and graphic software example.

RYD-8 RELAY DRIVER CARD...The RYD-8 relay driver card provides (8) relay driver circuits (TTL level input) for connection directly to relay coils which require currents of 3 amp or less per relay. The output of the RYD-8 is common emitter (a common positive feed to your relays or device). The RYD-8 will power relays with coil voltages from 5 volts to 48 volts DC. A terminal block is provided for connection to relays and relay power input. Other devices may be directly powered from the RYD-8 (motors, lamps, solenoids, etc.). The device must operate on a DC voltage between 5 and 48 volts and require 3 amps or less. The RYD-8 is available with optional LED indicator lamps for the outputs and/or a TransZorb/self-resetting fuse (specify the /L or /T option when ordering). Requires power supply with voltage output equal to relay coil voltage. Dimensions...2.25" by 4.875".

AR-4 RELAY SELECTOR...The AR-4 relay selector allows one of four possible on-board relays to be energized (similar in function to a four position DPST selector switch). Only one relay will energize at a time and one of the four relays will always be energized when power is supplied to the AR-4. Typical uses include telephone line selection, audio channel selection etc. Relays are DPST reed relays with a 10VA 200 volt rating. Available for connection to USB, WiFi, RS-232, RS-485 or Ethernet. Dimensions...3.25" by 4.25". Please contact EECI support for additional details

PAC-A RELAY INTERFACE PACKAGE...The AR-16 relay interface package is an assembled package which includes the EN-A plastic instrument case (10" by 7.5"), the AR-16 relay interface, (1) RH-8 relay card, power supply, connecter cable and software. The serial cable supplied will be the CC-DE9S unless specified otherwise.

PAC-D LOAD CONTROLLER PACKAGE... This relay interface package is a pre-assembled industrial duty controller which includes the AR-16 Relay Interface, the RL-8 relay card with 15 amp double throw relay contacts which are shunted together to provide increased reliability, LED indicator lamps for each control relay, dual power supply, serial cable, TransZorb/MOV surge protection, heavy duty metal enclosure and heavy duty 12 gauge 120 volt AC power cord. Eight 120 VAC electrical outlets are side mounted in the enclosure for connection of up to eight loads. A DE-9 socket (female) is provided for connection to the RS-232 serial cable. A power switch is provided which will allow a manual bypass of the control relays (with power to the AR-16 removed, all electrical outlets will be energized). Use to control power to office equipment, lighting, computers and a variety of other types of equipment and machinery. The serial cable supplied will the CC-DE9S for connection to the computer unless specified otherwise. Size 12" by 12".
