Rev 00 Rev 00 D-632 D-632 The FlexMod Family of Products Common FlexMod Applications TM The FlexModTM family is a series of small, robust electronic modules. They have two inputs (one analog and one digital) and two solid state outputs (one 10A, one 200mA) that can be programmed to do almost any job. TM Easy snap-in wiring with standard sealed connector Two outputs, two inputs Compact unit 3" x 4" x 1" In-Cab Radio 48540 Smart Battery Isolator Controller The FlexMod unit monitors two battery banks and controls one or more relays or contactors to make sure starting power is protected by isolating the starting and auxiliary battery banks. See Cole Hersee Hot Feed D-632. 48541 Electronic Voltage Sensing Relay & Timer The FlexMod unit monitors both battery voltage and ignition status, shutting down non-critical loads when the cutoff voltage is reached, or at the set time after the ignition is turned off. It is a timer and voltage sensor in one easy-toconnect unit. See Cole Hersee Hot Feed D-633. Engineering Panel Lights Battery • Rated for more than 1,000,000 on-off cycles – unit operates for the lifetime of the vehicle. Solid state technology gives long life and low maintenance. • Provides overvoltage and overcurrent protection to every direct load in that circuit– gives extra levels of protection. LVD Light Bar Radios Computers LVD LVD • Small lightweight sealed design – Uses less space; mounts outside or inside. Saves money by eliminating other hardware, and provides better wire routing. VSRT FlexModTM Dimensions Typical Application 3 Combined timer/voltage shutoff for police vehicles Cordless Light Charger Battery 48541 FlexMod VSRT combines two functions in one small unit that opens up options for mounting in a small space, and simplifies wiring and other components. The FlexMod VSRT protects starting power with simultaneous sensing of time and voltage.

A second 48610 FlexMod LVD can manage other loads, and if mounted close to the loads, will minimize wiring runs. LVD LVD • Factory programmable unit is highly versatile: with a broad range of presets available to match any special application. Custom Electronic Modules Do you have a specific electronic need that cannot be easily met with one of our off-the-shelf modules listed above? Do you need custom modules reliably built on a tested hardware platform that is rugged enough for commercial vehicles? Contact your Cole Hersee distributor or representative and we will design a FlexMod to solve your problem. Or contact Cole Hersee at firstname.lastname@example.org. Compartment Lights • Ultra low 1mA standby current means minimal battery drain – especially valuable when vehicle is in storage or not in use. Use the 48610 FlexMod LVD to protect starting power, and save fuel (and fines!) by eliminating idling. By connecting safety signboard (or other loads) to the LVD, the signboard can be safely be allowed to run with the engine off, without the risk of a dead battery. By connecting the horn or external alarm to the alarm circuit, the vehicle operator will be warned of impending shutdown. Flashlight Charger Horn Radios & Computer Typical Application 1 Idle reduction for work vehicles Battery • Simple wiring, accepts snap-in standard sealed connector – unit is easy to install. Part number with -01 suffix includes wiring harness. • FlexMod is auto-ranging – automatically senses the voltage of the system (12 or 24V) and selects the presets appropriate to that voltage. Single unit means less stock and fewer SKUs. (Timer 48636 is dual voltage, 12 or 24V). LVD Microrelay Sealed to IP67. Can be mounted anywhere 48610 Electronic Low Voltage Disconnect The FlexMod unit prevents the internal lights inside a trailer from being left on and draining the battery. Vehicle operator operates a momentary switch which turns lights on, allowing safe operation inside the cargo compartment. After 20 minutes the FlexMod flashes the lights and gives the operator increasingly urgent warnings to either exit the cargo compartment or reactivate the timer before the lights go out. See Cole Hersee Hot Feed D-631. LVD External Alarm Ultra-low standby current 48636 Electronic Timer for Interior Lighting Traffic Arrow Board Optional Relay We have created some standard units (see below) to meet specific application needs. If one of these fits your needs, but you need custom parameters, Cole Hersee can program them into your FlexModTM at our factory. The FlexMod unit preserves battery charge and protects battery banks by automatically disconnecting loads when battery voltage drops to a critical level. See Cole Hersee Hot Feed D-630. Cole Hersee designed these units to solve problems in many industries. Here are a few of the thousands of potential applications. Contact us with your specific application requirements. 1.31 [33.3] Battery 2 Bilge Blower The 48540 FlexMod Smart Isolator Controller turns an existing solenoid charging system into a smart system. The FlexMod protects the alternator with priority charging, and allows shore power connected to the house battery to charge the starting battery as well! The 48610 protects batteries from damage.
