Anaheim, CA – Component-level products remain an essential element for a complete automation solution. Continuing the series of announcements from Automation Fair, this article details new Allen-Bradley component-level products and enhancements from Rockwell Automation .

1761-NET-ENI Series B and 1761-NET-ENIW Series B enhancements include Ethernet interface module.

1791D CompactBlock I/O configurable, analog expansion block works with any CompactBlock base on DeviceNet and Remote I/O. The 16-point block is designed to provide feedback to the controller on errors, such as open wires, and is equipped with LEDs to show operating status. CompactBlock I/O combines network adapter, I/O circuitry, and terminations.

Three additions to the MicroLogix family include a MicroLogix 1000 10-point controller, RTD and Thermocouple modules for the MicroLogix 1200, and MicroLogix 1500 controller that supports up to 16 expansion modules for applications that require greater I/O expandability or have SCADA and special I/O requirements.

Insulation Displacement Connection (IDC) terminal blocks increase connection reliability by using a two piece cutting and connection system and address a number of common wiring issues, such as electrical isolation, small control wire connections, shock, and vibration.

PanelView 300 Micro and 300 Keypad Operator Interfaces are designed for applications that require small, low-cost operator interface solutions.

Pico Controller enhancements include new 12-volt dc Pico controller opening the door to 12 V battery applications. New expansion blocks allow Pico controllers to address applications with up to 38 digital I/O (the DC input units support analog I/O).

1492-SP protectors are designed to meet the branch circuit protection standards of the U.S. UL489 and Canadian CSA 22.2 No. 5.1 applications that incorporate power-limited circuits and control circuits, and are designed to protect load devices such as controllers, solenoids, power supplies, and control transformers from damaging power surges.

700-HL terminal block relay , with leak current suppression circuits (LCSC), is designed to interface between a TRIAC PLC or SLC programmable controller output and a field device (sensor, actuator, solenoid-enabled signal). By keeping the relay coil turned off when the I/O signal is low, the 700-HL relay helps combat nuisance issues created by current leakage.

Bulletin 900-TC temperature/heater controllers feature flexible, multi-function control, LED displays, plus auto-tuning and self-tuning capability.

Ultra3000 servo drive integrates with ControlLogix and communicates to the controller through a SERCOS fiber optic link and includes support for high-resolution feedback encoders as well as multi-turn absolute encoders to maintain position during power loss.
