OCSXL-Series

Supported Applications

The Omega OCS XL Series is a compact, all-in-one controller integrating a graphical operator interface (HMI), programmable logic control (PLC) ladder logic, built-in I/O, networking capabilities, and removable mass data storage. Designed for machine control and process visualization, the series combines these functions into a single unit suitable for OEM machine control and plant monitoring applications.

Operating Conditions & Performance

The OCS XL Series operates within an ambient temperature range of 0 to 50°C (32 to 122°F) with a power supply requirement of 12/24 Vdc. The enclosure rating is NEMA 4X (IP66) equivalent, and the unit features removable terminal blocks for electrical connections.

Measurement capabilities include support for J, K, N, T, E, R, S, B thermocouples and Pt100 RTD sensors, alongside analog inputs of 0 to 10 Vdc, 4 to 20 mA, 0 to 20 mA, and 100 mV. Accuracy is specified as ±0.2% (Warm Up Time of One Hour) generally, with a specification of ±0.3% below -100°C for specific ranges.

Resolution varies by input type: 16 bits for thermocouple and RTD inputs; 14 bits for universal analog inputs; 12 bits for analog outputs; and 10 bits for standard analog inputs. The response time is defined as one update per ladder scan plus 10 mS.

Measurement Ranges by Sensor Type

• B/R/S: 0 to 1600°C (32 to 2912°F)
• E: -200 to 900°C (-328 to 1652°F)
• T: -240 to 400°C (-400 to 752°F)
• J: -210 to 750°C (-346 to 1382°F)
• K/N: -240 to 1370°C (-400 to 2498°F)

Configuration Options

The series is available in three form factors distinguished by display resolution and physical dimensions:

• XLe Series: 128x64 pixels; Dimensions: Height 95.1 mm (3.7"), Width 95.1 mm (3.7"), Depth 63.9 mm (2.5"); Weight: 0.354 kg (12.5 oz).
• XLt Series: 160x128 pixels.
• XL6 Series: 320x240 pixels; Dimensions: Height 143.6 mm (5.65"), Width 186.1 mm (7.33"), Depth 88 mm (3.46"); Weight: 0.751 kg (26.5 oz).

I/O Configurations and Outputs

Models offer various I/O densities including DC/relay, DC/DC, high-density DC/DC, and universal analog options.

• Digital Inputs: 12 or 24 inputs compatible with 12V/24 Vdc; up to 4 inputs per model can be used for High Speed Counting (HSC) at a switching rate of 10 kHz totalizer/pulse, edges.
• Relay Outputs: Up to 6 relay outputs with continuous current ratings ranging from 3 A to 5 A depending on the series and model.
• DC Outputs: Sourcing/10 K pull-down; up to 12 or 16 points at 0.5 A per point, with some models supporting PWM/pulse outputs (up to 2 channels).
• Analog Inputs: Selectable between thermocouple, RTD, 0 to 100 mV, 0 to 10 Vdc, and 4 to 20 mA.
• Analog Outputs: Available on select models (e.g., HE-XE105), selectable between 0 to 10 Vdc and 4 to 20 mA with a minimum load of 1 kΩ for the 10V output.

Communication & Connectivity Options

The series supports CsCAN Network Port, MJ 1 Serial Port, and MJ 2 Serial Port. Field-installable communication options include:

• HE-XEC: 10/100 Ethernet Option Kit (includes deeper plastic back cover for XLe).
• HE-XMC: 57.6k Telephone Modem Option Kit.
• HE-XRC9: 900 MHz RF Modem Interface.

Data Storage & Programming

The controller supports removable MicroSD™ memory cards (1 GB capacity via HE-MC1) for data storage or program upload. The series is programmable using the Cscape software package, which includes a USB memory stick with symbol library and programming cables.

Key Product Differences

The OCS XL Series differentiates models by display resolution (XLe, XLt, XL6) and I/O architecture. The XLe series offers compact dimensions suitable for smaller panels, while the XL6 provides a larger 320x240 pixel interface with expanded physical size.

Model Number Distinctions

• XLe Series (HE-XE1xx): Includes HE-XE102 (DC/relay I/O), HE-XE103 (DC/DC I/O), HE-XE104 (High-density DC/DC I/O with 24 digital inputs), and HE-XE105 (Universal analog I/O).
• XLt Series (HE-XT1xx): Mirrors the XLe I/O configurations but features a larger display resolution.
• XL6 Series (HE-XL1xx): Includes HE-XL102 through HE-XL105 with similar I/O options; note that relay outputs on XL6 models are rated at 3 A continuous current, whereas XLe and XLt relay ratings vary up to 5 A.
• No Local I/O: The HE-XL100 model is available without local I/O, requiring expansion modules.
