Curtis offers ECS Module – Electronic Code Switch

The new Curtis ECS module is a flexible, easy to implement, operator identification keypad. The unit ensures only authorized users have access to the machine guaranteeing safe control and secure operation. Operators may identify themselves in multiple ways: through use of a personal pin code, through compatible RFID tags or a combination of the two.

The ECS module is flexible to implement and can easily be integrated into machines with or without a CAN bus. The module incorporates a buzzer and two easy to read status LEDs providing the operator audio and visual feedback regarding identification acceptance and diagnostics. Integrates easily into any system.

For CAN based systems: CANopen implementation with an optionally connected CAN termination resistor. Supports CAN baud rates from 100Kbps to 1 Mbps. For non-CAN based systems: output relay will change state to indicate authorized access. The Curtis ECS module operates in demanding conditions with IP65 front and IP40 (upgradable to IP54) rear ingress protection. It is CE compliant, UL recognized and ROHS2 Compliant.

Key specifications include: 12 to 96 V Nominal Voltage; 9V Min; 120V max. System Voltage: 12 to 96 V, Typical (mA) 25; Max (mA) 136.

Curtis Introduces New 1238 ‘SE’ AC Controllers

The new 1238SE controller models complete the ‘SE’ series of Curtis AC controllers (inverters). These models are available in four variants and utilize the latest technology to increase the peak current ratings for each size of controller. The Curtis SE range is ideal for the speed and torque control of 3-phase AC motors and intended for use as electric traction or hydraulic pump motor controllers for mobile, on-vehicle applications that require 24-96 VDC nominal battery supply. This ‘SE’ series is configured to work with any AC induction or PMAC motor. The new controller offers easy to use auto-characterization setup and simple on-truck pairing with different Induction motor types. A comprehensive library of induction and PMAC motor types are conveniently stored in the controller memory.

The Curtis 1238SE controller is CE marked as a programmable safety device under EN ISO 13849-1. These controllers meet or comply with relevant US and International Regulations of EN 12895:2015. They are designed to the requirements of: EN1175-1:1998+A1:2010 and EN (ISO) 13849-1 2015. Additionally, 1238SE is IP65 Rated per IEC 60529 and UL recognized per UL583.

Tom Howland joined as an active member of the American Red Cross Disaster Action Team (DAT)

Tom Howland becomes an active member of the American Red Cross Disaster Action Team (DAT). DAT is the first on-the-scene Red Cross contact at the site of a disaster. Tom’s experience with different charitable organizations has given him a great perspective on the value of giving his time and support in addition to making charitable donations.

"I realize more than ever now how important it is to be prepared for the unexpected things in life.  We can plan all we want, but let’s face it: a lot of events happen in life that are not planned.  The American Red Cross knows this better than any organization I have come across. Quick reactions to mobilize shelters in disaster areas immediately following floods, fires, natural disasters, and more takes plenty of help, resources, and support to help those in need."

Please join us in supporting the American Red Cross by making a direct donation
